The Fundamental Theorem on Symmetric Polynomials: History's First Whiff of Galois Theory

Ben Blum-Smith, Samuel Coskey

We describe the Fundamental Theorem on Symmetric Polynomials (FTSP), exposit a classical proof, and offer a novel proof that arose out of an informal course on group theory. The pa…
